我在服务器上安装了一个名为 node.js 的程序来监听端口 8088
我的服务器是来自 hostgator 的 VPS 包级别 3。
现在我正在尝试创建一个 init.d 脚本,以便 node.js 与系统一起自动运行,并且如果自动崩溃可以重新启动。
在谷歌上搜索了一下之后,我发现了一些资源并混合了一个 init.d 脚本。如您所见,它更像是复制粘贴工作:) 我遇到了很多问题,这很可能包括 init.d 脚本的 sysntax 错误。

我真的很困惑,因为不同的系统使用不同的方法。我的本地 ubuntu 使用了一个叫做 upstart 的东西,但我的服务器似乎没有 upstart 并且只使用 init.d 脚本。
如果我发出“uname -a”,我会得到:
Linux onl.onlyfreelancer.com 2.6.18-028stab070.14 #1 SMP
Thu Nov 18 16:04:02 MSK 2010 x86_64 x86_64 x86_64 GNU/Linux
另外,我似乎找不到像“insserv”这样的工具来启用这个 init.d 脚本。那么,如果我的 init.s 脚本是正确的,我该如何正确设置呢?
非常感谢任何帮助,我已经与这件事斗争了 2 天,但还没有运气。
